had mine for about weeks already been in the shop times once for some issue with the starter and a gear in the tranny getting caught together and then not starting the other because it fried the electrical cord to the trailer and occasionally the bunk head wont work and the bendixcruse will randomly decide to not work was in freightliners for about months before only had one issue and that was due to the weather being so cold it froze up the grease on the th wheel so it wouldnt lock
